PCA9600 demonstration board OM6293

1. Introduction

The OM6293 evaluation board features RJ45 jacks for easy setup and demonstration of the bus buffer capabilities of the PCA9600. It can be easily connected to other boards with off-the-shelf telephone or networking twisted pair wires.

The IC communicates to the host via the I2C-bus/SMBus port and extends the buses’ capacitive handling, increases the current handling, extends the range, and/or allows I2C-bus signaling via differential bus hardware.

2. Features

A complete evaluation platform for the PCA9600

Easy to integrate daughter card

Convenient test point for easy scope measurements and signal access

3.Getting started

3.1Assumptions

Familiarity with the I2C-bus is recommended. It is also recommended that the user read Application Note AN10658, which covers other design considerations such as timing delays, maximum data transmission speeds, handling ground potential differences and designing for extreme ESD requirements.

3.2 Static handling requirements

CAUTION

This device is sensitive to ElectroStatic Discharge (ESD). Therefore care should be taken during transport and handling. You must use a ground strap or touch the PC case or other grounded source before unpacking or handling the hardware.

3.3 System requirements

The OM6293 daughter card can be used with the Windows based OM6275 I2C 2005-1 demo board, the microcontroller-based OM6299 industrial reference design board, or stand-alone in the user’s application.

3.4 Power supply

When connected to the OM6275 I2C 2005-1 demo board or the OM6299 industrial reference design board, the OM6293 can draw power from the host board through the 5 V pin on connector 3 (CON3).

An external power supply can also be used to power the board at location J1. The external power supply can range from 2.5 V to 15 V.
